Title: Liq-gas delivery at constant pressure esp at wellhead - by sepg the phases, increasing pressure of each and remixing for removal at same rate as introduction to separator
IPC: E21B43/34
Filed: 1974-08-21
Abstract: Increasing the pressure of a liquid-gas mixt. e.g. that derived from a producing oil field, by (i) sepn. of the liquid and gaseous phases in a suitable separator; (ii) withdrawal of the liquid phase and increase of its pressure to a desired value by means of a pump, while maintaining the liquid level in the separator approximately constant by means of a level controller regulating the delivery of the pump to a mixer; (iii) withdrawal of the gaseous phase and increase of its pressure to a selected value by means of a compressor, and thereby holding the gas pressure in the sepn. more or less constant at a value equal to that of the original mixt. by means of a pressure regulator controlling an auxiliary pipeline for the return of gas to the separator and (iv) the supply of the liquid and gaseous phases so produced to the mixer which opens into a single channel for producing a mixt. at an increased pressure and at the same flow rate as at the inlet to the separator. Permits delivery of the oil/gas mixt. at constant pressure despite wide variations in the pressure at the well head.

Title: Inexpensive nickel alloy for dental prostheses - contg. chromium, iron, silicon, aluminium and boron
IPC: A61K6/847
Filed: 1974-10-04
Abstract: Alloy of metals which are non-precious, stainless and non-toxic, intended for composite dental prostheses, replacing alloys of metals which are precious, too expensive, too heavy, insufficiently rigid and with inferior adhesion to ceramics. The pref. alloy is (a) light, due to a high Ni content; (b) rigid, due to the pptn. of chromium carbide; (c) stainless, because it contains 23% Cr; (d) adheres to ceramic because it contains Fe + Al + Mn; (c) provided with deoxidants e.g. Mn and Si; (f) of increased strength and with better castability due to the addn. of boron; (g) non-toxic, due to the complete absence of Be. the alloys are used for metal-ceramic structures which are lighter, stronger and have longer life than conventional prostheses.

Title: Anchor for balustrade panels on concrete bases - has wedge-shaped discs rotated for vertical alignment
IPC: E04F11/18
Filed: 1974-12-02
Abstract: The anchor (1) is for a balustrade panel (7) comprising a frame with parallel vertical bars. It has slots and fasteners for holding the panel and has a base plate (2) which must be horizontal.

Abstract: 1531294 Battery testing COMPAGNIE EUROPEENNE D'ACCUMULATEURS SA 30 June 1976 [30 July 1975] 27178/76 Heading G1U The state of health of a battery (as opposed to its state of charge) is determined by fully charging the battery and by observing how rapidly its open circuit voltage drops to a stable value. A typical lead-acid cell in good condition will have an open circuit voltage of about 2.3V when just charged. This voltage MA, Fig. 1, will drop to a stable value of a little over 2.1V after about 10 hours. However, for a defective cell A such as one having an internal short passing about 100mA, the stable voltage is reached more quickly. This phenomenon is exploited in the present invention to test new, just charged, multicell batteries. In the preferred embodiment Figs. 3 and 4 (not shown) the open circuit voltage of each cell of a just-charged multicell battery is compared with the average cell voltage, and if the difference exceeds a pre-set amount, for example after 1 hour, the cell in question is judged to be defective.

Abstract: The active sound attenuation system is for ventilation ducts. Loudspeakers are used to cancel out the noise in the duct (1) due to the ventilation fan (2) etc. At some plane (P), sufficiently far from the noise source for the sound waves to have plane fronts, an acoustically and geometrically symmetrical acoustic dipole is positioned. It consists of two back-to-back coupled loudspeakers (5a,5b) mounted outside of the duct, and connected via convergent ducts (4a,4b) to orifices (3a,3b). An acoustic monopole, also consisting of a loudspeaker (10) connected via a convergent duct (12) to the main duct, is mounted on the plane P. The loudspeakers in the dipole are driven in antiphase by an amplifier (6) via a phase shifter (8) from a microphone (7) upstream in the duct. Drive to the downstream loudspeaker (5b) is also connected to the monopole loudspeaker (10) so that these two are in phase.
